4 Claims. This invention relates to advertising devices and is particularly adapted for advertising razor blades and the like.

The primary object of the invention is to direct a cutting blade through a suitable testing material cutting portions therefrom, demonstrating the keenness of the blade, in a continuous cycle of operation.

In our new and improved advertising device a rip of paper is intermittently progressed into the path of a cutting blade, the blade shearing off a portion thereof on each cycle of operation.

Another object of our invention is to provide :a mechanism for passing `a blade through a continuous strip of paper that is being intermittently fed into the path of the blade, the operation of which is visible to the onlooker demonstrating the keenness and durability of the cutting edge of the blade.

A further object of our vision of an attractive display sign in the proximity of our blade advertising device, said sign being caused to flash by timing mechanism within the advertising device.

These and other incidental objects will be apparent in the drawing, specification and claims to follow.

Referring to the drawing:

Figure 1 is a front perspective view of our new :and improved advertising device for blades.

Figure 2 is a plan sectional view, taken on line 2 2 of Figure 1, looking in the direction indicated.

Figure 3 is an end sectional View, taken on line 3-3 of Figure 1, looking in the direction indicated.

Figure 4 is a plan View, partially broken away to illustrate the flashing sign mechanism.

In the drawing:

Our new and improved advertising device for blades consists of a suitable cabinet I, having a roll of paper 2 journaled to the spindle 3, the spindle 3 is lxedly secured to the base 4. The end of the paper 5 of the roll 2 is threaded through the clamp 6 and extends beyond the clamp at 1. The side 8 of the clamp 6 is secured to the base at 9, and supports the pivotally mounted side I of the clamp 6 at II to the side of the clamp 8. The end I2 of the clamp I 0 bears against the paper 5 and the side 8 at I3, securely gripping the paper therebetween by the action of the spring I4. The spring I4 bears against the upright pedestal I5 at I6, and maintains a pressure against the clamp I0 for holding the paper.

invention is the pro- Ihaving its one end The paper 5 is fed through the clamp from the roll 2 between the feed 'roller I1 and pressure roller I8, the pressure roller I8 is mounted to the spring supports I3, which are xed at their one end to the shaft 2l) at 2I and 22., having their opposite ends Xedly secured at 23 and 24 to the upright pedestal I5. The pressure of the 'roller lI8 may be varied by rotating the upright pedestal I5 about its axis and locking the same by the lock nut 25, in the desired position. The operation of the feed roller and the clamp for progressing the paper through the same will be described later. y Two discs 26 and 21, having 'gear teeth 28 on their periphery, are geared together by the pinion 29. The pinion 29 is mounted to the stub shaft 30 and runs freely thereon. A motor 3'I drives the speed reduction gear 32,l whose driving shaft 3 3 has the disc 21 mounted thereon. The disc 21 drives the pinion 2'9 and the disc 26 in the 'direction of the arrows.

A blade holding arm 34 is journaled to the stub shafts 35, which are fixedly secured to the face of the discs 26 and 21, this blade holding arm travels in a rotary horizontal line, which provides a shearing cut by the blade 36 through The blade 36 is clamped within thumb nut 38 on the end of the arm 34. The disc 26 is mounted to the shaft 39 and journaled in suitable bearings 40.

A special cam 4I is xedly secured to the shaft 38 and is for the purpose of feeding the paper 5 through the clamping assembly 6 which is done manner. A ratchet gear 42 is secured to the upper end of the feed roller I1 and is operated by the pawl 43 which passes through the guides 44. The cam 45 forces the pawl 43 to the left in Figure 2, rotating the feed pawl to starting position.

When the feed roller I1 is rotated the 6 is released at I3, therethrough. In I3, a plunger 41 is clamp permitting the paper to feed order to release the clamp at mounted within the guides 44, contacting the arm 48 of the pivotally mounted side member I0 of the clamp 6, and its opposite end contacting the cam surface 49 of the cam 4I. Both the pawl 43 and the plunger 41 are operated simultaneously so that as the clamp is released at I3 the ratchet will feed the paper therethrough at the same time.

The electric collector ring assembly 58 distributes electrical energy from the terminal 5I to the brushes 52 and 53, which control the operation of the lamps 54 and 55, these lamps are located within the housing 56 directly behind the transparent sign member 51. This electric collectorring assembly may be timed for any desired result, for instance the XYZ, the name of the blade, may rst appear to the observer under a lighted condition, next the word blades may be illuminated, thereby giving the eifect of a flashing sign.

We will now describe a cycle of operation of our new and improved advertising device forV blades. The motor 3l drives the discs 26 and 21 continuously, operating the blade holding Y.

arm so as to slice off the portion 1 of the paper 5, as the paper is intermittently fed 4out through` the clamp 6 at I3 by the feed roller l1, After the blade 36 has completed a cut the cam assembly 4l operates the pawl 43 against the ratchet 42 and the plunger 41 against the arm 48 of the clamp B, releasing the clamp at I3 and feeding the paper therethrough at the same time.

When the cam 48 leaves the ends of the pawl 43 and the plunger 41 vreleasing the clamp allowing it to securely grip the paper at I3, the blade will pass through the paper 5 slicing oif the portion 1 of the end of the paper. This operation is continued as long as desired and provides an effective form of advertising, The portion 1 accumulates in front of the machine in great quantities, demonstrating the keenness and the durability of the cutting blade.

We do not wish to be limited to the particular mechanical construction illustrated, as other forms of mechanical embodiment may be employed, still coming within the scope of the claims to follow.

What is claimed as new is:

1. A demonstrating advertising device for razor blades, including a cabinet, an arm movable over and beyond one wall of the cabinet,

means mounted in that wall and connected to the arm, said means being visible through the wall and operating to compel a combined longitudinal and transverse movement of the arm 5 relative to and substantially parallel with the wall of the cabinet, a razor blade holder at one end of the arm to move the cutting edge of a contained blade substantially in parallelism with the cabinet wall, means projecting through the 10 wall of the cabinet to support a length of material to be severed in the path of movement of a razor blade when in said holder, and mechanisms wholly concealed in said cabinet for actuating the arm-operating means and feeding material through the material supporting means.

2. A construction as dened in claim 1 wherein the mechanism for feeding the material holds the material at rest during that operation of the arm acting to compel a cutting movement of a carried blade.

3. A construction as defined in claim 1 wherein the mechanism for actuating the arm compels an arm movement forwardly and downwardly for material-cutting action of a carried blade, and then rearwardly and upwardlyto move a carried blade wholly free of the material.

4. A construction as dened in claim 1 wherein the mechanism for actuating the arm compels an arm movement forwardly and downwardly for material-cutting action of a carried blade, andv then rearwardly and upwardly to move a carried blade wholly free of the material, and wherein the mechanism for feeding the material advancing the material into the view of the observer and the cutting movement of a carried blade is operated while the arm and carried blade is moving rearwardly and upwardly. i 40 PHILLIP C.
